PAUL RICHTER, or TENAFLY, NEW JERsEr. PROCESS OF PADDING AND ORNAMENIINGBURLAP 0R SlMlLAR FABRlCS.

Specification of Letters Patent. Application filed June 13, 1906. SerialNo.-321,456,

lap or Similar Fabrics, of which the following is a specification.

This invention relates to an improved process of padding and coloringburlap, buckram, or similar coarse textile fabric and of pro-'ducingupon said fabric simultaneously with the coloring operation anysuitable ornamental design.

In the accom anying drawings, Figure 1 is a cross-section o theprincipal parts of an apparatus for carrying my invention into effect.

ig. 2 is a face view of a fabric treated by my process, the threadsbeing not round-shaded to more clearly bring out the deeper coloringbetween the threads; and. Fig. 3, an exaggerated cross-section on line 33, Fig. .2.

The apparatus for racticing the invention consists of two para lelcylindrical rollers'4 and 5, journaled side byside and pressed towardeach other by suitable means. (Not shown.) The roller 4 is engraved, asat 6, to contain an intaglio or sunk representation of the design to betransferred to the burlap, buckram, or similar coarse textile fabric 7.Roller 5 is a true or unbroken cylinder, so that though exerting apressure against the convex surface of roller 4 it-cannot exert anpressure upon the sunk ortions 6 of end roller. Centered above tli therollers is a vessel 9, containing a suitable sizing and coloringcomposition 10. Vessel 9 is open at the bottom and extends partly overboth of the rollers, so that the composition will flow u on the latterand into the trough formed; y the contiguous halves of the rollers.Rotary motion being imparted to, say, roller 4, the fabric 7 will bedrawn over roller 5, through vessel 9, into and.

through pass 8, and thence out below roller 4. During this operation thesunk portions 6 of roller 4 while passing .tbrough'vessel 9 will becomefilled with composition ,10 anterior to reaching pass 8.

While fabric 7 is drawn through vessel 9, and before reaching pass 8, itwill become covered with composition 10. When the fabric reaches pass 8itis subjected to a State of New Jersey,-have.

itssurface, the design 11 being,

e pass 8 betweensevere ressing or squeezing action at all points etweensurface of roller 5 and the convex portion of roller 4. In this way thecomposition is forced through the pores of the fabric to pad the same,while it is simultaneously ressed off the raised parts of the groundworand returned in part to vessel 9,

thus leavingbutalightsurface-coloring. This surface-coloring of thegroundwork is shaded, being lighter where the pressure isgreater-i. e.on top of the threads-and darker where the pressure is less-i. 6.,between the threadsso that the threads will be lighter than theintersticesbetween the threads, 2.

While roller 5 squeezes out an partly returns the composition from thosepoints of the fabric that lie across the convex portion of roller 4,portions of the fabric which extend across the sunk sections 6 of suchroller. The consequence is that the composition pocketed by such sunksections will be transferred within pass 8 in a heavy layer to thefabric and will remain intact upon such fabric. In this way there istransfixed upon the fabric a design 11 corresponding to design 6 andformed by the same composition 10 that serves to color however,considerably heavier than the surface-coloring. After the fabric haspassed through the machine and has been dried it is ready for use.

If it is desired to produce shaded designs 1 1, the sunk sections. 6 ofroller 4 are made to vary in depth.

It will be seen that by my invention I pad and surface-color the fabricand simultaneously produce uponthe same a suitable design with the samecomposition, but applied in a heavier layer than goesto form thesurface-color. Thus anovel and useful product,

available for a large number of'purposes, is

obtained in a simple and economical manner. My process may also beapplied to paperfabrics, which for the purposes of this invention areequivalents of textile fabrics.

What I claim is- 1. Process of treatin sists in passing the fabricthrough a sizing and coloring composition to form a groundcolor, andsimultaneously fabric a pattern by a heavier layer of said composition,substantially as specified.

2. Process of treating a coarse fabric,which it will not similarlyaffect those a fabric, which conapplying to said consists in passing thefabric throngh a sizing Signed by ine at New York city, Manhatandcoloring composition to form a groundtan, New York, this 12th day ofJune, 1906. color, applyingto said fabric a pattern by a v heavier layerof said composition, and simul- PAUL E 5' tan'eously shading theground-color by sub- Witnesses:
